Witches are not magically adept humans, they are their own race entirely. They are born with varying degrees of magical potential, but not a specific talent. Witches are unique in the way that they can create magic, as opposed to having magical abilities. They are spell casters who work with the wild magic that roams all planes of existence. They can create wondrous things, but it takes time for them to do so. They are limited by their power, adeptness, and knowledge.
